Cisco 7925G Administration Guide

DHCP Settings
The Cisco Unified IP Phones enable DHCP, by default, to automatically assign IP addresses to devices when
you connect them to the network. If you do not use DHCP in your network, then you must disable DHCP and
manually enter the network configuration information.
Use these guidelines when manually configuring the IP settings:
•
Ensure the TFTP server has an IP address.
•
Ensure the default router IP address is on the same subnet as the host IP address.
When DHCP is enabled, you cannot configure IP settings, but you can configure an alternate TFTP server.Note
